In alphahull: Generalization of the Convex Hull of a Sample of Points in the Plane

alphahull 3.0.1

• Replaced the interp triangulation with geometry::delaunayn (Qhull) in delvor(). Delaunay edge adjacencies and Voronoi edges now come from the same triangulation, with a convex-hull consistency check.
• Oriented unbounded Voronoi rays using the sample centroid and extended their finite plotting markers beyond the midpoint projection when necessary.
• Updated plot.delvor() to draw the Delaunay mesh directly from mesh.
• Backward compatibility: The structure of delvor(...)$tri.obj has been preserved as a triSht-compatible object to maintain compatibility with existing code and dependent packages, while Delaunay triangulation is now computed using geometry.

Development notes

• Parts of the code and documentation were revised with the assistance of AI tools.
